PIERPONT T. LANGDON, OF AUDUBON, MINNESOTA.

CAR-AXLE LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 742,041, dated October20, 1903.

Application filed December 31, 1902. Serial No. 137,359. (No model.)

To all whom it may concern.-

Beit known that I, PIERPoNT T. LANGDON, a citizen of the United States,residing at Audubon, in the county of Becker and State of Minnesota,have invented certain new and useful Improvements in Oar- AxleLubricators; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention is an improved car-axle lubricator; and it consists in thepeculiar construction and combination of devices hereinafter fullydescribed and claimed.

The object of my invention is to effect improvements in the constructionof the means for lubricating the journals of caraxles, whereby the samewill participate in the end thrusts of the car-axles and will maintainthe waste at all times in close engagement with the axle-journals andprevent the waste from coming out of contact with the axle-journals,hence assuring an efcient lubrication of the axle-journals under allconditions when the train is in motion and` prevent waste of thelubricant, excessive wear of the journals and bearing-blocks, and alsoprevent the -boxes from heating.

In the accompanyingdrawings, Figure l is a vertical central longitudinalsectional view of a car-axle box provided with my improved lubricatingdevices, showing the same applied to a journal of a car-axle. Fig. 2 isa transverse sectional view of the same, taken on the plane indicated bythe line a a of Fig. 1. Fig.

l3 is a detail perspective view, partly in section, of the oiling-pan.Fig. 4 is a transverse sectional View of my improved lubricatingdevices, showing the same applied to a modified form of car-axle box, ofwhich the oilingpan forms the lower side.

In the embodiment of my invention here shown the car-axle box 1 and thebearingblock 2 in the upper side thereof and which engages the upperside of the journal 3 of the car-axle are of the usual form, 4indicating the door at the front or outer side of the box, which doorishinged at its upper side, as at 5, and is engaged at its lower side by aspring-catch 6 on the underside of the caraxle box when the door isclosed.

Incarrying out my invention I provide an oiling-pan 7 of suitabledimensions, which is adapted to be placed in the lower portion of thebox 1 under and at a suitable distance from the journal 3 and which ishere shown as provided with a pair of longitudinally-dis posedoil-reservoirs 8, which are connected at their front or outer ends to anintake or supply-nozzle 9,which is common to both of them and throughwhich oil is supplied to said reservoirs. In the center of the pan is aspace 10 between the oil-reservoirs for the reception of waste 11,employed to convey the oil by capillary action from the oilpan to theunder side of the axle-journal, the Waste being supplied with oil fromthe reservoirs 8 through perforations 17 and the pan having its sideportions 12 extending upwardly for a suitable distance to adapt the panto hold or contain a sufficient quantity of the waste. The oiling-pan issupported in the car-axle box in such manner as to keep the waste at alltimes in contact with the axle-journal by means of springs, which adaptthe oiling-pan to conform to the end thrusts or longitudinal motions ofthe car-axle and also adapt the oilingpan to conform to any radialmovements of the axle-boxes with reference to the axle-j ou rnal.Within-the scope of my invention these springs maybe of any appropriateconstruction, and I do not desire to limit myself in this particular. Inthe form of my invention'here shown the said springs 13 are coil-springsdisposed transversely under the oiling-pan and having their endsconnected to the sides of the axle-box, as at 14. The

pan, as shown, is provided with lugs 15 on its under side, which engageO ppOsite sides of the said suspending coil-springs, which lugs preventthe springs from becoming disengaged from the oiling-pan by the motionsof latter, as will be understood.

It will be understood that the tension of the springs which formsuspending-supports for the oiling-pan is such as to keep the latter soelevated as to prevent the waste fromA disengaging the under side of theaxle-journal under any condition when the train is in motion. It will befurther understood that ICO erence to said suspendingsprings andlongitudinally with reference to the axle-box, so that the oiling-panmay participate in the end thrusts of the car-axle, and hence at alltimes keep the waste which supplies the lubricant To the axle-journal inengagement with the latter. Moreover, the movements of the oiling-panthus permitted by the supporting-springs prevent the waste from becomingpacked or solidiiied in the oiling-pan and prevent its capillaryproperties from being impaired from this cause.

In the modified form of my invention shown in Fig. 4 the axle-box l isbottomless, and its side Walls are provided With longitudinal andvertical guide-slots 16, the under sides of which are open to receivethe upwardly-extending side walls of the oiling-pan. Hence the latterforms the lower side of the box.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without reqniring a more extendedexplanation.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

In combination with a car-axle box and an axle jonrnaled therein, a panunder the axle and coil-springs disposed transversely under the panextending from side to side of the axle-box and having their endsattached thereto, said springs supporting the pan and adapting the sameto move with the axle, said pan being adapted to contain waste andprovided with a reservoir to supply lubricant by gravity to thewaste andbeing further provided on its under side with devices which engage thesprings and prevent casual disengagement of the pan from the springs,substantially as described.

In testimony whereof l have hereunto set my hand in presence of twosubscribing witnesses.
